When graphing an absolute value inequality, such as -4 ge x le 4 does that mean 2 lines since you have two inequality signs?

    \[-4 \ge x \ge 4 \] rather

    haha ok so x can be any value between -4 and 4. so in this case only one line is needed

    But it can't be -3 through 3, so it would seem like 2 lines on an x,y graph.

    ok sorry then yes it would be like you have 2 solid lines at x=-4 and x=4 with everything in the middle shaded

    wouldn't it be everything outside shaded? since it can't be -3 to 3, it would be everything else, right?

    if the inequalities were switched then you'd be right
